Where to use L2 Restricted Zone Key in Koschei Complex DMZ

Unlock the secret exfil.

The Koschei Complex bunker in Call of Duty: Warzone DMZ houses several hidden explorable areas and discoverable easter eggs. If you've come across a keycard called the L2 Restricted Zone Key, I've described in this guide what exactly is its purpose and where it can be used.

The L2 Restricted Zone Key unlocks the cyan-colored doors like the one shown in the above image. These locked rooms can be found specifically in two sections of Koschei Complex: Alpha Cluster and Factory Admin. While the former can be accessed using a Car Battery and Jumper Cables, for the latter you'll need a Factory Admin Room Key.

These areas are, well, L2 Restricted Zones inside which you can find some rare valuables required for missions. Most importantly, these rooms can be used to call in an exfil separate from the two elevators that are marked on the map for every player. I suggest you keep one or two L2 Restricted Zone Keys in your key stash as you will need them for some Redacted faction missions.

After entering an L2 Restricted Zone you'll have to take out some Riot Shield enemies and possibly a sentry turret. There will also be some laser traps inside the room. You can either crawl under them or carefully disable them unless you'd like to be blown up by a C4 charge.

L2 Restricted Zone Keys are pretty easy to find if you're looking in the right place. I've acquired these keycards multiple times from vintage desks and other loot caches in Koschei Complex. You can even purchase it from the shopkeeper in the Factory Admin section for $50,000 or trade it for 4 Wrench and 2 Scientist's Notes. Furthermore, you'll receive L2 Restricted Zone Keys as a completion reward for Abandoned Operator and Brother In Arms missions for the Tier 4 Redacted faction.
